Когда тюнер старой школы сталкивается с пределом возможностей штатной системы управления Bosch Motronic, Siemens и др. перед ним встает классическая дилемма: мучиться с записью чипов, прошивать через разъем или «свапнуть» систему на Январь, Megasquirt, Vems, ECUMaster и т.п. Но сегодня есть третий путь, который объединяет заводскую надежность с гибкостью спортивных ЭБУ. Речь об эмуляторах CobraRTP.
online ECU setup
New project: Flash Online - flash memory emulator (29F200 / 400 / 800)
Due to numerous requests, the development of a new project was started: a real-time memory emulator for ECUs with 16-bit flash memory, such as 28F200 / 400/800 and 29F200 / 400/800 (256-1024kB).
Assigned targets:
- Live tuning! Editing ot the MAPs/full ROM in real time mode.
- Online software support - TunerPRO RT
- Support for hardware table / map tracing (Address hit tracing)
- Work with any software through CobraRTP Utility, (read / write firmware in .bin format)
- The ability to upload and use 2 firmware (full) with subsequent switching in real time without the participation of a PC (dual mode Dual-mode)
What does it give and what is the difference from “firmware” via OBD connector (in boot mode)?
Indeed, most ECUs with this type of memory (except 28Fxxx) are easily "flashed" through the diagnostic connector (OBD), which does not require intervention in the hardware of the control unit. But, if you need not just load the finished firmware into the ECU, but adjust the ECU for an engine with a non-standard configuration?
TunerPRO RT Tutorial
Introduction
In this article we will talk about tuning ECUs Motronic (Bosch), GM, DSM (Mitsubishi), Jetronic, etc.: BMW, Audi, Volkswagen, Volvo, Chevrolet and not only, with external EPROM memory: 27c128, 27c256, 27c512, 27f512, etc. This is a relatively outdated ECU cars 80-90-ies. Many tuners will say that the ECU data is not "chipable” or setting up ECU data is very difficult, and the best solution is to install a "sports" control unit such as MegaSquirt, Vems, AEM, Haltech, etc., but due to the hardware primitiveness, fortunately, there are currently ways for these cars to fully configure online. For this purpose, there are memory emulators that allow you to detect the memory chip with the ability to change the memory dump (ECU firmware) in real time using special software for editing calibrations. The advantages of setting up a standard control unit, as opposed to installing an external one, are: maintaining a standard diagnostic system; no need to replace or rework standard wiring; no need to replace or supplement sensors; no need to coordinate on-board control units with the engine ECU.
